Hyphen and Underscore for SEO Redux字号，并强调对搜索引擎优化Redux

This is an important update to a post that appeared on September 12, 2007.这是一个重要的更新后出现在9月12日， 2007年。

It seems that Google still doesn’t like underscores, as the big G’s spam czar Matt Cutts said in a post on his blog:看来，谷歌仍然没有想强调，作为大G的垃圾邮件沙皇马特卡茨说，在后在他的博客：

People thought that underscores are the same as dashes to Google now, and I didn’t quite say that in the talk. 人们认为，底线是一样的破折号，以谷歌现在，我并没有完全说，在交谈。 I said that we had someone looking at that now. 我说，我们已有人看，现在。 So I wouldn’t consider it a completely done deal at this point. 所以，我不会认为这是一种完全木已成舟在这一点上。 But note that I also said if you’d already made your site with underscores, it probably wasn’t worth trying to migrate all your urls over to dashes. 但是注意，我也说，如果您想您已经取得了突出的网站，它可能是不值得尝试迁移所有的网址给破折号。 If you’re starting fresh, I’d still pick dashes. 如果你已经开始新鲜，我还是选择破折号。

I write a regular column for a major publisher.我写常柱的一个主要出版商。 The system utilizes a fantastic CMS (content management system) but one thing about it that has always bugged me since I was first shown the ins and outs is that image and other filenames have to have underscores rather than hyphens.该系统采用了美妙不育系（内容管理系统） ，但有一件事它一直窃听我，因为我是第一次表明，里里外外的是，图像和其他文件名必须有底线，而不是连字号。 Eg file_name.jpg not file-name.jpg.如不file_name.jpg文件name.jpg 。 Of course, I always use a descriptive tag with the file_name but that doesn’t help in terms of SEO if the file_name itself is rendered as a single nonsensical entity in Google’s eyes, rather than being separated into two meaningful words and hence a useful keyphrase - file-name - by the hyphen.当然，我总是使用一个描述标记的文件名，但无助于从搜索引擎优化，如果文件名本身就是提供作为一个单一的荒谬实体谷歌的眼睛，而不是分成有意义的词，并因此有用keyphrase -文件名-由连字号。

What would be ideal would be if Matt were to tell us that the Google algorithm now treats the _underscore_ as a word separator equivalent to the -hyphen-, but unfortunately, it seems, it does not.什么是理想的，如果将马特是告诉我们，现在谷歌算法对待_underscore_作为一个词分离相当于，字号， ，但不幸的是，似乎没有。 This means that all those file_names will be seen as file-names or more explicitly “file names” and will not gain the relevance of that keyphrase, which is still lost on Google.这意味着所有这些file_names将被视为文件名称或更明确地“档案名称” ，并不会得到相关的keyphrase ，它仍然失去了对谷歌。 This is bad news for the Sciencebase site, which has a lot of legacy pages that used underscores in the html page names.这是个坏消息的Sciencebase的网站，其中有很多传统的网页上突出使用在HTML的网页名称。

Nevertheless, in that same talk, Matt recommended various optimization techniques for Wordpress bloggers (which apply equally to every website, to be frank):然而，在相同的交谈，就提出了各种优化技术的WordPress的博客（这同样适用于每一个网站，坦率地） ：

He recommended using a plugin or hack that swaps the name of the blog title with the name of the individual post title, this has always been the case for Sciencetext.他建议用插件或黑客工具，用来换名称的博客标题的个人姓名，职称，这一直是如此Sciencetext 。

He said everyone should use the “Alt” attribute while blogging and with photos.他说，每个人都应该使用“备选”属性，而博客和照片。 This is important not only for SEO but for vision-compromised readers.这一点是重要的不仅是搜索引擎优化，但对视觉的影响读者。

Interestingly, Google does not care about the number of slashes in a URL (blog/title/date/#), so bloggers needn’t worry about the permalinks and sub-folders unless they’re concerned with Yahoo ranking, apparently Yahoo still does care about slashes.有趣的是，谷歌并不关心一些斜线的网址（博客/标题/日期/ ＃ ） ，所以博客不必担心的永久性和子文件夹，除非他们担心雅虎排名，显然还没有雅虎关心斜线。

Another interesting point that emerged is that Google essentially ignores file extensions in a URL in terms of ranking (.php, .html, .htm, .asp, .aspx, .jsp are all seen as equivalent. But, don’t use .exe, that’sa special case and dangerous for SEO.另一个有趣的一点，出现的是，谷歌基本上忽略文件扩展名的网址中的排名（ 。 PHP中， 。 html文件， 。热媒， 。动态。如需， 。 JSP的都被视为等同。但是，请不要使用。程序，这是一个特殊情况和危险的搜索引擎优化。

One final point, if you are hoping to get your blog into Google News you must have multiple authors, but everyone knows that don’t they?最后一点，如果你希望得到您的博客到谷歌新闻您必须拥有多个作者，但大家都知道，这样做不是吗？

Just for the record, these tips were first (I believe) reported by Loren Baker公正的记录，这些提示是第一次（我相信）报告的罗兰贝克 here这里 . 。
